The max reverse voltage for that diode is 600 V
Using it like you have described will very easily exceed that.
Although there is an inductor in the way, inductors have capacitance, fast pulses will bypass it easily.
Tantalum caps have a structure that makes them miniature thermite bombs.
Once punctured they can go with style.
A full circuit diagram is required, i do not fancy trying to converting a fritzing diagram first unless i am very bored.
